Using deep learning to recover depth information from a single image has been studied in
many situations, but there are no published articles related to the determination of
construction site elevations. This paper presents the research results of developing and
testing a deep learning model for estimating construction site elevations using a drone-
based orthoimage. The proposed method includes an orthoimage-based convolutional
neural network (CNN) encoder, an elevation map CNN decoder, and an overlapping …
